Product Details

Size: 1.625 Inch x 8.625 Inch

Fastest operation under short circuit conditions, let-through currents are typically 20% lower with a corresponding let-through energy (clearing I^2t) up to 40% lower than the next fastest class L fuse

Time delay for high inrush loads such as motors and transformers without nuisance opening

Most current limiting for lowest peak let-thru current even at fault currents up to 300 Kilo-Amp

Pure silver links ensure lowest let-thru current and longer fuse life

Rejection style design prevents replacement errors

High-visibility orange label gives instant recognition

Fiberglass body provides dimensional stability in harsh industrial settings

Detailed Description: Ferraz Shawmut Amp-Trap 2000® Class L Fuse operates at a current rating of 400 Amps and voltage rating of 600 VAC. It has an interrupt rating of 200 kilo-Amps AC and 100 kilo-Amps DC. Fuse offers a time-delay of minimum 4 seconds at 500% of rated current providing ultimate protection. Fuse body is made of fiberglass that offers greater stability in harsh environment condition. It offers protection to downstream circuit components against short circuit current. It has catalog number embossed for ease identification. It measures 1.625 Inch x 8.625 Inch. Fuse is UL listed, CSA certified and is RoHS compliant.

Catalog Description Amp-Trap 2000 A4BQ fuses are more current limiting than any other Class L fuse on the market. When correctly coordinated, they bring a superior level of protection to service entrance equipment. Downstream circuit components have maximum protection against short circuit let-thru current. A4BQ's built-in 4-second time-delay characteristic (at 500 percent of rated current) accommodates harmless inrush currents with no nuisance opening. 600 Volts 400 amps A4BQ series.
